The waivers are some of the last remaining provisions of a landmark 2015
nuclear agreement between Iran and world powers that the administration of U.S.
President Donald Trump withdrew from last year. Under the 2015 deal, Tehran
pledged to curb its nuclear activities in exchange for international sanctions
relief.

Pompeo told a news conference on November 18 that the waiver for Iran's Fordow
site will be eliminated in mid-December. Iran has recently stepped up uranium
enrichment at the facility.
